Let’s say that someone you know needs you to give him a ride. This person is having an emergency. You have a car, but, with a dead battery, it’s not taking anybody anywhere. Let’s say that your car was given to you, too. Some guy gave it you because he loves people, and he figured you’d use the car to bless others. The idea is that our faith in Christ has a purpose to it. It is living—because Jesus lives. It works. It is good for something. If faith from Jesus Christ comes into one’s life, but brings no tangible blessing to others, it differs fundamentally from the faith that Jesus and his apostles demonstrated.
What good is it, dear brothers and sisters, if you say you have faith but don’t show it by your actions? Can that kind of faith save anyone? James 2:15 (NLT)
